It would be a good idea if you altered the specification to include these mods., and we would be glad if you would send us say three copies of the modified specification. This will simplify ordering, and serve to keep us up to date. Further we would like you to supply by return, one pair of hydraulically damped pistons and dashpots complete, suitable for H.V.5 carbs.
